Features
Silicone rabha rudzi rutsva rwepolymer elastic zvinhu, ine yakanakisa kupisa tembiricha (250-300 ° C) uye yakaderera tembiricha kuramba (-40-60 ° C), yakanaka kugadzikana kwemuviri, uye inogona kutsungirira yakadzokororwa mamiriro akaomarara.Uye mamiriro ekuuraya hutachiona, nekusimba kwakanyanya uye kudiki kudiki deformation (200 ℃ 48 maawa asingasviki 50%), breakdown voltage (20-25KV/mm), ozone kuramba, UV kuramba.Radiation kuramba uye humwe hunhu, yakakosha silicone rabha ine mafuta kuramba.
application
1. Kufambisa: inoshandiswa mumhizha yekuvaka ngarava.
2. Redhiyo uye mota: muindasitiri yekufonera.
3. Inoshandiswa muindasitiri yezviridzwa nezviridzwa.
4. Kushandisa muindasitiri yezvendege.
5. Inokodzera midziyo yemumba, kuvheneka, kurapwa, kunaka uye kugadzira bvudzi, nezvimwe.
Kusiyana nePVC pombi
Silicone chubhu imhando yechubhu yerabha, isingaite mafuta uye isingadzipi kupisa.Machubhu erabha ane akawanda maapplication nekuda kwemhando dzakasiyana dzerubha.Zvinowanzoshandiswa rubber chubhu zvinhu zvinosanganisira EPDM, CR, VMQ, FKM, IIR, ACM, AEM, etc. Zvimiro zvakajairika zvinosanganisira single-layer, double-layer, multi-layer, uye yakasimbiswa, isina kuvandudzwa, nezvimwewo.
Chekutanga, silica gel ndeyezvinhu zverabha, PVC ndeyepurasitiki zvinhu, iyo huru yePVC pombi ndeye polyvinyl chloride, uye iyo huru mbishi yesilicone pombi isilicon dioxide.
1. PVC pombi inogadzirwa nepolyvinyl chloride resin, stabilizer, lubricant, nezvimwewo, uye yozobudiswa nehot-press injection molding machine.Iyo huru yekuita, magetsi ekudzivirira;kugadzikana kwakanaka kwemakemikari;kuzvidzima;kubatwa kwemvura yakaderera;nyore kunamatira Connection, inogona kumira tembiricha yepamusoro ye40 °.Midziyo mikuru igasi rekumaindasitiri, kutakurwa kwemvura, nezvimwewo, pombi dzesuweji dzemumba, pombi dzemvura, nezvimwe. Nyaya dzekuchengetedza kwezvakatipoteredza: Zvishandiso zvikuru zvekubatsira zvakaita semapurasitiki uye anti-kuchembera zvinowedzerwa zvine chepfu.The plasticizers in daily-use PVC plastics anonyanya kushandisa dibutyl terephthalate, dioctyl phthalate, etc. Izvi makemikari Zvigadzirwa zvine chepfu.
2. Silicone tubing, iyo silicone zvinhu ine yakagadzikana makemikari ehupfumi, haibatike nechero makemikari zvinhu kunze kweakasimba alkali uye hydrofluoric acid, ine yakanaka makemikari ehupfumi, yakanaka magetsi ekudzivirira kuita, haisi nyore kuzera uye mamiriro ekunze, zvinhu zvakapfava, zvakatipoteredza. uye zvinhu zvisina chepfu, Zvisina Ruvara uye zvisinganhuhwi.Mapombi emumba achagadzirwa nesilicone zvinhu, inonyanya kushandiswa mumidziyo yemumba, indasitiri yekurapa, indasitiri yemaindasitiri, indasitiri yemotokari zvichingodaro.
Chinhu chikuru chesilicone hose ndechekuti inopesana nekushanduka kwekushisa kubva -60 degrees kusvika ku250 degrees, asi mutengo unodhura zvikuru.PVC inowanzo shandiswa semapombi emvura akajairwa, anonzwira tembiricha, akachipa uye anonhuwa, anokodzera nharaunda dzekushanda, uye haana zvinodiwa pamapombi.Pressure-resistant silicone machubhu anogona kumira kumanikidzwa, asi PVC iri pakati, zvichienderana nekukora kwemadziro uye caliber.Iyi ndiyo misiyano pakati pesilicone machubhu uye PVC machubhu.
